Look at Figure 2. What is the measure of x ? ( Hint: you may need to use triangle ACE to help you;) notice the right angle??? NEED HELP ASAP PLEASE

60°

Step-by-step explanation:

Let angle BAE = angle ACD = x

                                BCD  = AEC = 60°

EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°

                                 EAC = 60° - x

                                 BAC = EAC  + BAE = 60° - x + x = 60°

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
